Authorization
The server/application decides whether the caller may execute the operation.

Model Context Protocol standardizes how a compatible AI host/client discovers and uses exposed tools, resources and context. For business, the value comes from controlled interoperability, not “unrestricted AI access.”
It is a business application that exposes some of its capabilities through an MCP server/interface, allowing a compatible AI client to discover and invoke them in a structured way. MCP does not replace application authorization, validation, business rules or audit.
The protocol addresses the interoperability problem; the application remains responsible for what is actually allowed.
Request path
01
The user or agent workflow defines a task.
02
The client discovers the exposed MCP capabilities.
03
AI selects an appropriate tool and prepares arguments.
04
The server/application validates permissions, input and business rules.
05
The operation returns a structured result the client can use.
Interfaces
| Features | MCP | Traditional API | Automation workflow |
|---|---|---|---|
| Primary purpose | AI-tool interoperability | Programmatic integration | Orchestrate process |
| Consumer | Compatible AI clients/hosts | Software developers/services | Workflow engine |
| Capability discovery | Protocol-supported | Usually documentation/schema driven | Preconfigured nodes/actions |
| Execution logic | Client/agent chooses tools | Caller code | Defined graph/rules |
| Permissions | Application-controlled | Application-controlled | Workflow + app controls |
| Best fit | Expose bounded tools/context | System-to-system integration | Repeatable business process |
Control plane
The server/application decides whether the caller may execute the operation.
Arguments and state are checked before execution.
Transaction and lifecycle logic should not depend only on a prompt.
High-impact actions may require a human gate.
Tools can have bounded scope and operational limits.
Tool calls, results and failures should be observable.

Adstic Orb
CRM, store, funnels, email, booking and other modules contain application state.
The MCP layer can expose specific permitted operations to a compatible client.
Application validation and permissions determine what can actually be executed.
When you want an AI client to work with business software through structured capabilities instead of making every operation a custom prompt plus ad-hoc integration. A typical architecture is AI host → MCP interface → permitted tool → application validation → result.

FAQ
No. MCP describes an interface/capabilities. Actual access depends on exposed tools, authentication, permissions and application controls.
Not necessarily. API and MCP can coexist and serve different consumers and integration patterns.
No. The agent/host decides how to pursue a bounded goal; MCP can be the interface through which it discovers and uses tools.
For production use cases, useful records include tool name, caller/context, validated arguments, result status, errors, approval events and timestamps according to security/privacy requirements.
A good MCP layer exposes exactly the required capabilities and keeps authorization and business rules in the application.
